Abstract

The invention relates to a device having an orifice covered by an optical device (3), which is to be prevented from being dirtied. For that reason the device comprises a housing (1), in which a ring-shaped socket (2) supporting the optical device is rotatably journalled by means of a bearing arranged around the periphery of a socket (2). Moreover, the socket (2) is provided with a rim turbine blades (8) against which one or more jets of pressure air from nozzles (10, 11) in the housing (1) are directed.

Description

508 772 2 att passera genom en uppvärmningsanordning innan den tillförs nämnda dysa eller dysor, vilket gäller speciellt om anordningen är utsatt för fukt och kyla, exempelvis vid en tillämpning som siktruta på en farkost eller ett fordon. Den varna luften kan då förhindra hopfrysning av de rörliga och fasta delarna. 508 772 2 to pass through a heating device before it is fed to said nozzle or nozzles, which applies especially if the device is exposed to moisture and cold, for example in an application as a sight window on a vehicle or a vehicle. The warning air can then prevent the moving and fixed parts from freezing.

Uppfinningen är närmare tydliggjord i det följande under hänvisning till bifogade ritning, scnxschematiskt visar en som exempel vald utföringsform av en anordning enligt uppfinningen, och på vilken Figur 1 är en vy uppifrån, figur 2 är en vy underifrån med en bottenplatta bortskuren för tydlighets skull av det i Figur 3 i perspektiv visade utföríngsexemplet med en sektor bortskuren för åskådliggörande av anordningens inre, och Figur 4 är en V tvärsektion genom anordningens hölje och övre delen av optikens fattning med endast ett fåtal av lagringens kulor och turbinblad utritade.The invention is further elucidated in the following with reference to the accompanying drawing, schematically shows an exemplary embodiment of a device according to the invention, and in which Figure 1 is a top view, Figure 2 is a bottom view with a bottom plate cut away for clarity of the embodiment shown in perspective in Figure 3 with a sector cut away to illustrate the interior of the device, and Figure 4 is a V cross section through the housing of the device and the upper part of the optics socket with only a few of the bearing balls and turbine blades drawn.

Den på ritningen visade anordningen har ett hölje l och en i höljet roterbart lagrad, ringformad fattning 2, som båda är tillverkade av genom- synligt plastmaterial. I fattningen 2 är en optik i form av en glasskiva 3 monterad. Fattningen 2 är vidare formad med ett periferiellt spår 4 och höljet l med ett motsvarande spår 5, i vilka spår 4,5 lagringskulor 6 av stål är belägna. På fattningens 2 undersida är en krans 7 av turbinblad 8 av metall anbragt. Vid två diametralt motsatta ställen av höljet 1 är, såscnnantyds schematiskt i figur 2, två tangentiellt mot turbinbladen 8. riktade dysor 10,11 anordnade med axiellt riktade anslutningar 12,13 för tryckluft, vilka senare är visade i figur 4. Den ena 11 av dysorna 10,11 visas även i sektion i figur 3.The device shown in the drawing has a housing 1 and an annular socket 2 rotatably mounted in the housing, both of which are made of transparent plastic material. In the socket 2, an optic in the form of a glass plate 3 is mounted. The socket 2 is further formed with a peripheral groove 4 and the housing 1 with a corresponding groove 5, in which grooves 4,5 storage balls 6 of steel are located. On the underside of the socket 2, a ring 7 of turbine blades 8 of metal is arranged. At two diametrically opposite places of the housing 1, as schematically indicated in Figure 2, two nozzles 10,11 directed tangentially to the turbine blades 8 are arranged with axially directed connections 12,13 for compressed air, which are later shown in Figure 4. One 11 of the nozzles 10,11 are also shown in section in figure 3.

Vid tillförsel av tryckluft till dysorna 10,11 riktas två strålar av tryckluft mot turbinbladen 8, varvid kransen 7 och fattningen 2 med glasskivan 3 försätts i rotation styrda av lagringskulorna 6. Tryckluften passerar förbi turbinbladen 8 och avgår genom en mellan fattningen 2 och höljet 1 befintlig spalt 14.When supplying compressed air to the nozzles 10,11, two jets of compressed air are directed towards the turbine blades 8, whereby the ring 7 and the socket 2 with the glass plate 3 are set in rotation controlled by the bearing balls 6. The compressed air passes past the turbine blades 8 and passes between the socket 2 and the housing 1 existing column 14.

Anordningen kan vara avsedd att sitta i spetsen av ett tubformat operationsinstrument och bakom höljets 1 bottenplatta eller, om denna är försedd med en öppning, bakom glasskivan 3 vara försedd med en mikrokaméra eller fiberoptisk anordning. Blod eller andra kroppsvätskor eller substanser S0m kCflUEr i kontakt med den snabbt roterande glasskivan 3 slungas åt sidan och glasskivan hålls ren från allt som kan nedsätta genomsynligheten.The device may be intended to be located at the tip of a tubular surgical instrument and behind the base plate of the housing 1 or, if this is provided with an opening, behind the glass plate 3 be provided with a microcamera or fiber optic device. Blood or other body fluids or substances S0m kC fl UEr in contact with the rapidly rotating glass plate 3 are thrown to the side and the glass plate is kept clean of anything that may impair transparency.

Eftersom lagringen av den roterbara optiken 3 har anordnats på den ringformade fattningens 2 yttre periferi blir anordningens genomsynlighet väsentligen sannanfallande med optikens 3 hela area markerad av de streckade 5GB 772 3 linjerna 15, som även markerar var en öppning i höljets l bottenplatta bör vara anordnad om höljet skall vara tillverkat av metall.Since the storage of the rotatable optics 3 has been arranged on the outer periphery of the annular socket 2, the transparency of the device becomes substantially true with the entire area of the optics 3 marked by the dashed 5GB 772 3 lines 15, which also mark where an opening in the bottom plate of the housing should be provided. the cover must be made of metal.

Uppfinningen är självfallet inte begränsad till det här visade och beskrivna utföringsexemplet utan kan modifieras på åtskilliga sätt inom ramen för den i patentkraven definierade anordningen. Sålunda kan den visade lagringsanordningen alternativt vara utformad som en magnetlagring eller luftlagring, vilka lagringar är väl kända inom denna teknik. Eftersom anordningen enligt uppfinningen även är användbar som siktruta på fordon eller farkoster kan den bli utsatt för frost, varför anordningen i ett sådant fall med fördel är försedd med en anordning för uppvärmning av tryckluften innan den tillförs turbinbladen och leds ut gemun spalten 14 mellan den roterande fattningen 2 och höljet 1.The invention is of course not limited to the exemplary embodiment shown and described here, but can be modified in several ways within the framework of the device defined in the claims. Thus, the storage device shown may alternatively be designed as a magnetic storage or air storage, which bearings are well known in the art. Since the device according to the invention is also useful as a sight window on vehicles or craft, it can be exposed to frost, so in such a case the device is advantageously provided with a device for heating the compressed air before it is supplied to the turbine blades and led out through the gap 14 between the rotating socket 2 and housing 1.
